Ecosoft FK 1665CE filter is an independent filter intended for reduction of iron, manganese, hardness, ammonium and organic matter in water.

The filter is commonly used for water purification in 3-4 bathrooms houses, inhabited by 5 to 6 residents. The filter vessel is filled with the Ecomix® advanced softening material and supplied with a multifunctional control valve and a brine tank for system regeneration.

The unique control valve is a product developed by Ecosoft and produced by Clack Corporation (USA). It provides filter’s independent service, keeps constant reserve of purified water and doesn’t require any special attention.

Key advantages

  • Fully automatic and noise-free

  • Uninterrupted delivery of clean and soft water

  • Durable and efficient operation during no less than 5 years

  • Cost-effective salt consumption and low volume of discharge

  • Quality guaranteed by the international CE and ISO certificates

Benefits of using filtered water

  • Clean water with no odors in every tap, shining sanitary ware, and utensils

  • Silky skin and healthy hair

  • Condition and colors of clothes and linens are preserved

  • Significant savings on detergents — up to 50%

  • Longer service life of equipment with heating elements (washing machine, dishwasher, boiler, and kettle)

Components of the filter

  • Filter vessel

  • Clack WS1 СЕ multifunctional control valve (USA)

  • Brine tank with brine system for regeneration

  • Ecomix® advanced softening material (Ecosoft, Ukraine)

The filter is connected to the cold water supply. Water pre-cleaned from sediment impurities enters the filter vessel filled with Ecomix® filter media. Ecomix® consists of five components that are self-classified into layers inside the filter during the regeneration. Water evenly passes through each layer, sequentially reducing the content of iron, manganese, organic matter and hardness. Purified water is supplied to consumer through the riser pipe of the filter vessel.

The filter effectively purifies water and independently controls all processes of its operation. When the filter media is exhausted, the filter independently starts regeneration, but only when water consumption is minimal, in order not to limit consumer’s access to the purified water. Besides, the system remembers the intensity of consumer’s water consumption at different times and adapts to make the clean water available even during peak consumption – at weekends, for instance.

Regeneration of the filter media is divided into 5 clearly predetermined stages that are carried out by the valve independently. The first stage is the backwash intended to wash out compounds of iron and manganese from the filter media. Then the brine solution is supplied from the brine tank to the filter vessel to pass through Ecomix®. As a result, hardness and organic matter are washed out and together with the remains of solution are discharged to sewers. The next stage (3) represents a short backwashing that ploughs up the filter media again and washes out the remains of brine solution. After regeneration, washing of the media is carried out with direct water flow (stage 4) for filter layers to self-classify in a correct order. The last stage (5) represents filling the brine tank with water to dissolve the tablet salt and preparation of the solution for next regeneration. After all that stages, the filter can be used again for water purification.

Thanks to the use of a multifunctional valve, the filter does not require constant attention. The only important task connected to maintenance for customer is timely stocking of the salt. It will ensure efficient regeneration of the filter media and thus durable filter service life and water quality.

If any problem arises, the valve will inform about the problem at the display with a text message containing contact information of service center.
