How to Disinfect Water Using Calcium Hypochlorite 

A.)  Dissolve 1  teaspoon 60-78% granular calcium hypochlorite in 7 - 8 liters of water .
B.) Then add this solution 1 part to  disinfect water to 100 parts water to be treated. Finally keep mixed water to settle completely for 20 - 30 minutes before drinking.

NOTE ::: Freshly prepared ( A.) solution is recommended to make 2nd step ( B.) drinking water.

Good day,

Kindly advise the chemicals required and quantity for cleaning of cargo holds (Panamax) loaded coal to grain standard.
Reply : 
1st segment to clean and neutralize coal rsidue :
Coal contain sulphur and many more others materials which is resulting corrosive effect on metal and painted surface. In chemical terms its proper cleaning means not only removal of its deposit to make surface clear and bright, But chemically neutralization effect also required. Our RX Tuff High foam ( Advanced formula of ALKAATUFF high foam ) having chemical neutralization formula as well as during cleaning process with high pressure machine resulting high dense foam to clean vertical surface of hold effectively.

2nd segment to prepare hold up to Grain standard :
After completion 1st step, if cargo hold can be rinse with diluted chlorine ( ppm level, 1 Ltr to 1000 Ltr Fresh water )  water followed by fresh water rinsing will result  cargo hold for Grain loading standard. 

3rd Required quantities :
For general cleaning each hold required 150 to 250 Ltr of RX Tuff High Foam ( New formula ) and 50 Ltr chlorine water ( Concentrated one up to 15% )

Note : Rusted and paint scale Area / part cleaning must required before using of any cleaner including 1st segment suggestion. For RUST REMOVING our product code is  ( RXSOL-16-1088-025 ) and for Paint removing chemicals our code is RXSOL-18-1013-025

General cleaning tips :

Preparing Cargo Holds for loading Grain depends on the previous cargo.

1. Cargo Holds must be thoroughly cleaned and dry and trace of previous cargo in frames, beams, girders, and other structure.

2. There should not be any loose rust and or paint scale anywhere in the Cargo Holds, Bulkheads, upper and lower hopper spaces, underneath of Hatch Covers and tank top.

3. There should not be traces of live & dead insect & weevils.

4. Bilge covers should be cleaned of any cargo residues and have enough drain holes. Bilge cover needs to be grain tight but not watertight.

5. Bilge well should be cleaned of previous cargo dray and odour free.

6. Bilge suction should be operational at all the times. 

Removal of cargo residue:

Air Blow from top using high pressure air to reach all accessible corners. Cargo to be swept, scrapped & collected in a drum. Attention to be given

• Australian ladder and its platforms and stanchions

• Beams and girders under cross decks

• Frames, beams, girders, and other structure

• Large pipes holding brackets behind the pipes

Then Cleaning and sweeping coal cargo from the hold as maximum possible by HELPER / Crew member

Loose Rust & Paint Scale:

A sharp hand scraper shall be used to take off the peeling rust & paint scale

Special attention to following areas:

• Australian ladder and its platforms, hand rails and stanchions

• Australian ladder and its platforms and stanchions

• Beams and girders under cross decks

• Frames, beams, girders, and other structure

• Large pipes holding brackets behind the pipes

• Hatch coamings and under hatch covers

• Booby hatches & cover

Tank top loose rust

Tank top should be free of loose rust and cargo residue

Any rust which can be scraped by hand scrapers should be removed.

The tank top should be rinsed with fresh water

Cleanliness of cargo hold bilges

Hold bilges must be cleaned thoroughly to remove all residue, rust particles and cargo stains etc.

The filter (Rose Box) must be cleaned thoroughly

The bilge well sections shall be washed with continuous running of sea water to remove all odour and later rinsed with fresh water

Estimation of total dissolved solids in water:

Requirements: Glass and plastic beaker Spirit lamp

Funnel and filter paper Boiling chips

Procedure:

. Filter the sample water.

. Weigh the glass beaker W1 g

. Take 50 mL of sample water in the glass beaker.

. Evaporate the water carefully until the glass beaker becomes dry.

. Cool and weigh the glass beaker with the boiling chips again, W2 g.

Calculation: Total solid (ppm) = (W1 – W2) x 2 x 104 Filterable residue:

Procedure:

. Weigh the empty glass beaker with boiling chips, W1 g.

. Filter the sample water into a plastic beaker.

. Pour 50 mL of filtered water into the glass beaker.

. Evaporate the water carefully until the glass beaker becomes dry.

. Cool and weigh the glass beaker with the boiling chips again, W2 g.

Calculation:

Filterable residue (ppm) (W2 – W1) x 2 x 104
Non-filterable residue (ppm) = total solid – filterable residue.

ALKAATUFF is also alkaline grade ship hold cleaning chemicals. Its major difference between simple alkaline cleaner and ALKAATUFF is foam and penetration power. ALKAATUFF contains high dense foam generation compound which helps to apply on a vertical surface for a LONG time ( 10 - 30 Minutes ) while Alkaline cleaner also have the property of foam but with large bubble which can't affect more than 30 seconds to 90 seconds. And ALKAATUFF contains ionic surfactant which helps to pentrate chemcials in residual cargo component. This is why ALKAATUFF is considered as the most effective Alkaline cleaner for ship hold cleaning. This is why marine chemical dealers tend to buy RXSOL ALKAATUFF more than any other alkaline detergent.

ALKAATUFF available at Mumbai, Kandla - Gandhidham, Visakhapatnam - Gangavaram, Kolkata - Haldia - Paradip, Chennai - Ennore, Fujairah, Sharjah - Abudhabi.

What is procedure to cleam Lime from ship hold surfaces?

LIME REMOVER HD  is concentrated liquid product specifically engineered to attack, penetrate and remove lime deposit from cargo hold. It is a liquid product designed to Clean and eliminate limestone caustic lime deposits and dry lime stains from cargo.

Best results can obtain on dry surface of LIME.  It break down the ionic bond in lime, releasing the lime from any surface to which it has adhered.

Lime Remover HD must be used according to the hold surface area that is to be covered, the extent of contamination, the available downtime and the application method being used. Lime Remover HD is covering 10-12 Squire Meter area.

Using Procedure

I - Spray Method

Spray Method is applicable where spray machine is available, suitable to process chemical solutions, is used with a 50% Lime Remover HD/water solution to SPRAY directly onto the surface area. Then, the solution must be left to act for 15 minutes followed by thorough rinsing using a high–pressure water supply source. After , the surface must be left to dry. The percentage  of dilutions may vary depending on the thickness and hardness of the deposited lime.

II – Soaking Method

Soaking is a method where Lime Remover HD is used undiluted and applied with conventional methods such as an elongated thick and hard brush, a hard sponge etc. Once applied, Lime Remover HD must be left to soak for 30 minutes. Rinse with water, and followed by leaving the surface to dry. Usually, this method is applicable to heavily contaminated small and large tank surface areas and installations.

Before cleaning of lime, we have to learn about lime composition and its bonding nature as well as dissolving properties of lime.
Lime is composit mixture of calcium and its powder state becomes lumps due to presence of moisture. Here it is clear that if you want to remove composed lime from surface calcium bond should be break. Means if we'll add such material on lime bonded surface which can weaken the bond of calcium, then cleaning of lime from surface will be easy.

Acid like muriatic, phosphoric, sulfuric etc easily breaking the bond of hardened calcium, but these acids are highly corrosive not only to handle but also dissolving iron metals, which is causing pit and roughness on metals surface.

Then again question comes how to remove lime without damaging the metal surface and also easy to use by personnel.

We worked on this concept and developed Lime cleaner remover with effective blend of corrosion inhibitors and we balanced acid with mixture formulations.

Lime cleaner save time to remove lime deposition from ship hold surface. And lime remover easily dissolves and break lime deposited hard bond also due to non fuming nature its application becomes easier.

We have lime cleaner standards packing is in 25, 50, 210 litre drum.
