SHELKA CHEM INDUSTRY

R.O. ANTISCALANTShelka Chem Industry is acknowledged for providing a full range of Reverse Osmosis Antiscalants to enhance the production of RO plant. The vast range is specially formulated for controlling the stalwart inorganic deposits on the RO membrane. In most of the water treatment plants and other industries, the antiscalant is best to minimize the particulate fouling. The liquid formulation is used for controlling the scale precipitates and keeps the membrane separation systems clean. Above all, the offered chemical is used for long run and prolonged the element life along with reducing the maintenance cost. This is the reason why antiscalant shows excellent results in process related to membrane separation counting nanofiltration, reverse osmosis, and ultrafiltration applications.The antiscalants work as an additive in the reverse osmosis system and enter the RO membrane. This chemical, in turn, causes a time delay in between calcium, magnesium, and bicarbonate. Because of this, the water gets easily pass through the membrane before the occurrence of any chemical reaction.

Features of RO antiscalants

• Effective working.
• Show a high recovery rate.
• Superb results.
• Highly used in producing potable water.
• Show its action even in a wide pH range.

RO MEMBRANE CLEANERSThe cleaning of the membrane entirely relies on two things, cleaning chemicals, and their effectiveness. The professional application, operation, designing and operation of cleaning equipment also play an important role in the effectiveness of the RO membrane cleaners. By using high-quality RO membrane cleaners, one can quickly reduce the maintenance cost and get the best result. It is very much advantageous if cleaning starts at the early stage as it prevents any fouling and irreversible damage. The product line of RO membrane cleaners is suitable for almost all kinds of membrane systems like food and beverage industry to avoid scaling and fouling.

To accomplish the diverse need of clients, Shelka Chem Industry offers a great range of RO membrane cleaners at cost effective prices.

 RO BIOCIDE/ALGAECIDERO Biocide or algaecide as the name suggests is suitable for every membrane system. This is very useful in reducing the growth of bacteria in the RO system. In actual, the offered range is specially formulated to show the action by penetrating the coloring surface. By doing this, it eradicate entirely the micro-organisms like bacteria, fungi, algae, and pathogens. On choosing the right biocide, you are promoting the membrane cleaning, lower down the overall cost or operation as well as maintenance cost. At Shelka Chem Industry, you can get both oxidizing and non-oxidizing biocides at reasonable prices. Even at the low dosage, it shows the required results. RO Biocide/Algaecide is entirely safe in use and acts against problems related to contaminating permeate quality and reduced flow rate.

Key benefits of RO biocide

• Present as high purity product.
• Increase the output of water quality.
• Simple handling.
• Safe to use.
• Easily eliminate the requirement of chlorination and de-chlorination of feed water.
• Biodegradable in nature.

RO DESCALING
RO Descaling offered by Shelka Chem Industry is a low foaming cleaning solution, which is formulated for cleaning the RO membranes. It is highly used for eliminating the colloidal silica, bacterial slime, clay, organic fouling, calcium carbonate, sulfate, fluoride, and iron. Being present as a buffered solution, this chemical is useful in maintaining the pH limit. Ro membranes can easily get removed without any trouble. The removal of biological or organic foulants can quickly be done at high pH making them disperse as both of them generally comprises of carboxylic functional groups.Important features of RO Descaling

• Get better results against the scales removal by just adding this chemical.
• Increase membrane life.
• Depict the excellent dispersing properties.
• Show superb system cleaning at both high and low pH.
• Brilliant action on removing silicates carbonates sulfates and irons fouling.
• Completely compatible with different types of membranes.
• There is a low foaming formulation.
• Effective in even low dosing.
• High recovery rate.
• Simple to use in recirculation method.
