WatPass® Nitrate & Hardness 4000

WatPass N&H 4000 - nitrate filtration and water softening system in cabinet housing.

This plant is a real innovation. The increasingly recognized problem of high nitrate levels in our drinking water finds with this plant the ideal solution for areas where the lime content of the water is also too high. The treatment of these two tasks, in one plant, is rarely found. We know of no other system that can do this. In addition, there is the comfortable operation by the high-quality Clack control head of the latest generation, with color display and multilingual menu guidance (DE, EN, ES, FR and PL). This is particularly low-maintenance, DIYers can usually replace the seals themselves. We recommend this approximately every 24 months.

Removing nitrate from water in particular is currently the greatest challenge in water treatment. Known solutions with filter cartridges or reverse osmosis systems are very complex and expensive due to the high follow-up costs. With the innovative WatPass N&H 4000 combination system you can free your well or house water from nitrates and reduce the hardness to a reasonable level in a very cost-effective way.

The filter media in the system, 10 liters for softening and 7.5 liters for denitrification (capacity 150g nitrate or 2.4 mol nitrate), are automatically and regularly regenerated. Due to the voluminous salt tank, you need to replace salt relatively rarely.

Combination unit WatPass N&H 4000 consists of:

A cabinet housing for a salt supply of max. 70kg. A quantity-controlled central control valve type Clack WS 1 CI IA, as well as an integrated fine cutting valve. Suction device and connection line to the central control valve. Integrated in the system, a GRP pressure bottle filled with high quality ion exchange resin.
