• Systems of removal of mechanical suspended substances and impurities from drinking water
• System for iron and manganese removal from drinking water
• Systems of softening of drinking water
• Systems on improvement of organoleptic features of drinking water
• Systems of removal of mechanical suspended substances, impurities, dissolved iron and manganese

		PURPOSE The system is destined at hardness salts removal: calcium and magnesium, as well as heavy metals of initial water to the norms required by Sanitary Inspection 2.1.4.559-96 “Drinking water”.
Short-grained ion resin

INITIAL DATA:

The present system operates providing there are no aggressive gases in the treated water: carbon dioxides, hydrogen sulfide and ammonia.

INTERGRATION

• body
• load
• pilot valve
• regeneration tank
• drainage system
  

Stainless steel pressure filter “PF” is used as body. Positive ion resin is used as load with the solution of sodium chloride for its regeneration. Regeneration tank is made of polythene or stainless steel. Ion resin usage involves positive ions displacement of calcium, magnesium and heavy metals for positive ions of ion resin.
For regeneration and load washing controlling mechanism is used, it is both automatically and manually operated. Radial drainage is used for pure water collection and washing, it is made of hard polyvinyl chloride resin or drainage covers of polyethylene or stainless steel.

ADVANTAGES:

• high water hardness removal capacity
• short-grained ion resin usage
• reduction of washing agents usage
• usage of regular sodium chloride as consumable material
• regeneration if automatic, after passing through the water system of certain quantity

Systems on improvement of organoleptic features of drinking water

		Purpose: Improvement of organoleptic features of water; Removal of chlorine and other organic compounds.
Granular active coal	Special macro porous Ion-exchanging resin

Complete set:


• Body;
• Loading;
• Control valve;
• Drainage system.

As a body a pressure filter "PF"made of stainless steel is used. As a loading active granular coal is used, that possesses a highly-developed active surface because of porosity. The selective physical sorption of coal happens due irreversible capture of high-molecular compounds by surface micro pores.

Modern technologies of production of activated coal, modified by Argentums ions, allowed increasing a resource of effective work of filters considerably. To carry out hand and automated ablution filters are equipped with a control valve.

Advantages:

• Does not require a filtering layer;
• Low operation costs;
• High efficiency of removal of organic admixtures, remaining chloride
• Long service term of activated coal under a wide range of temperatures;
• Several models of control valve for hand or automated return ablution.

SYSTMES OF MECHANICAL SUSPENDED SOLIDS, IMPURUITIES, DISSOLVED IRON AND MANGANESE REMOVAL

	PURPOSE Mechanical suspended solids, dissolved iron and manganese removal of initial water to the norms of Sanitary inspection 2.1.4.559-96
“Black” sand

The systems operates with total iron and manganese concentration not more than 15 mg/l

INTEGRATION

• body
• load
• pilot valve
• regeneration tank
• drainage system
  

Stainless steel pressure filter "PF" is used as body. "Black sand", sand, gravel are used as load. The solution of potassium permanganate is used for regeneration. Regeneration tank is made of polythene or stainless steel.

"Black sand" iron usage makes iron and manganese contained in water in the form of Fe²⁺ and Mn² transform into insoluble form of Fe³⁺ and Mn³ after manganese oxide oxidation and are held by load particles.

Fractional composition of sand and gravel are selected in such a way to provide maximum contaminant capacity and water treatment quality.

For regeneration and load washing controlling mechanism is used, it is both automatically and manually operated. Radial drainage is used for pure water collection and washing, it is made of hard polyvinyl chloride resin or drainage covers of polyethylene or stainless steel.

ADVANTAGES:

• no need for filter layer regeneration
• low costs at operation
• high efficiency of organic substances, surplus chlorine removal;
• long useful life of absorbent carbon at wide range of temperatures;
• Several models of pilot valve for automated or mechanical back-washing
