DIS Series Pre-Engineered Industrial Water Softener Systems

Design Criteria
Diamond Water's DIS systems are an integrated system design using the most reliable and serviceable components on the market today. All softeners are provided with an 8% crosslink industrial cation resin that offers low pressure loss and excellent stability over a wide range of operating conditions. The standard PVC lower distributor system provides corrosion resistant, trouble-free service, total resin bed utilization, even service flows and proper backwashing. A filter gravel support bed covers the lower distributor system to prevent intrusion of resin and wasted capacity.

Controller
Diamond Water standard controllers combine a pilot stager with a time clock, mounted and wired in a NEMA rated enclosure to initiate a regeneration. Cycle times are programmable to accommodate a wide range of applications. Push button and manual initiation is provided as a standard feature. Pilot stagers are pre-tubed to the diaphragm valves at the factory. A ball valve and y-strainer are standard on the inlet supply to the pilot stager. Twin alternating systems use a 16-port PVC pilot stager that provides a stand-by unit rinse down feature prior to going online as a standard feature.

Control Valves
Diamond Water systems utilize 'Y' pattern diaphragm valves, arranged in a valve nest, for control of the water flow through the system. The individual valves are operated by a pilot stager in the controller using either hydraulic or pneumatic pressure for a control medium. Valves are constructed of cast iron with rubber, stainless steel and brass internals. A pressure compensating drain line flow control is installed on each system to regulate the backwash and fast rinse flows over a wide range of operating pressures.

Brine System
Diamond Water dry salt brine systems are designed to provide maximum salt storage. The non-corrosive polyethylene brine tank houses a salt grid, brine well and 3/4" PVC commercial brine valve that allows for field adjustments for varying salt dosage. The PVC eductor is designed for maximum efficiency and reliability of both brine draw and refill. Brine tanks 54" and larger are constructed of steel with epoxy lining and primer exterior. A wet salt system is employed using a brine saturator, filtering gravel and an Aquamatic 3010B brine valve.

Resin Tanks
Diamond Water pressure vessels are constructed of welded carbon steel with a cold epoxy lining and primed exterior as standard. The vessels are rated for 100 psi working pressure and supported by steel strap legs welded to the bottom head. Vessels 48" and larger are provided with angle iron legs. A 4" X 6" hand hole in both the upper head and lower sideshell are provided on 20", 24" and 30" diameter vessels while an 11" X 15" manway in the upper head is provided on 36" and larger diameter vessels.
