The deionizer shall include acid and caustic systems for proper regeneration of the resins. Each system shall include an eductor to draw the chemicals from the day tank, rate control valves for the chemical draw lines, automatic shutoff valves for the dilution water and chemical draw lines, check valves with diluted chemical sample valves.  A hydrometer shall be used to allow monitoring of diluted chemical concentration.

RECIRCULATION SYSTEM

Recirculation pump and controls shall be furnished to maintain peak water quality during standby and low flow conditions. The pump shall also be used to eliminate the pre-rinse cycle costs.

DISTRIBUTORS

The DI tanks shall be fitted with inlet and outlet distributors.  The inlet distributor is a baffle type.  The lower distributor shall be constructed with the radial hub underdrain using high quailty schedule 80 PVC pipe and fittings, delivering flows unifomly over the entire bed with a minmum pressure drop. The ABS constructed laterals shall be self-cleaning allotted type constructed of polypropylene. The .010” PVC slotted laterals shall provide high flow rates with reiable service.

RESIN TRAPS

Resin traps shall be furnished on the outlet of the cation and anion vessels.  The resin traps shall be constructed of clear PVC and fitted with 20 mesh screen.

FLOW SENSOR

The flow sensor shall be provided to initiate regeneration based on water use to increase efficiency and prevent high conductivity bypass during periods of high water use. Flow sensors shall be highly repeatable and have open collector signal with a wide dynamic flow range of 0.1 to 6m/s. Electrical requirements shall consist of: Supply voltage 5 to 24 VDC, supply current <1.5 mA @ 3.3 to 6 VDC / < 20mA @ 6 to 24VDC. Output collector, sinking 10 mA max.

The sample valves shall be ¼ brass ball valves.

SKID MOUNTED AND PRE-PIED

The DI mineral tanks shall be skid mounted on a 4" or 6" channel iron skid. The skid shall be cross-braced with 4" or 6" channel or angle iron with legs for an elevated skid. All steel surfaces shall be coated to the match exterior of softener tanks.  All interconnecting piping shall be the same material as the valve nest manifold piping, and shall be assembled to the fullest extent possible. The inlet and outlet isolation valve connections, brine and drain headers shall terminate inside the skid internal area. All piping shall be suitably supported and anchored to the skid. All electrical wiring shall be complete between the units, and the hydraulic or pneumatic tubing shall be installed as part of the skid package. The entire skid mounted system shall be leak and electrically tested as a unit by the manufacturers

OPTIONS

The following options shall be available to meet specific application requirements:

  1. CUSTOM TANKS.  ASME code stamped vessels, and custom designed tanks are available.
  2. WASTE NEUTRALIZATION.  Waste neutralization systems shall be available to neutralize the pH of the DI waste prior to discharge.  The systems shall be designed for either manual or automatic operation.
  3. PIPING AND VALVES.  Alternate valves, piping materials and distributor systems shall be furnished when required.
  4. DEGASIFIERS.  Degasifiers shall be furnished to strip carbon dioxide from the cation effluent.  This reduces the load on the anion exchanger which decreases the anion vessel size, resin volume and caustic consumption.
  5. RESIN.  Alternate resin types such as weak acid cation and weak base anion resins shall be available to partially deionize the water.  The weak acid cation and weak base anion resins shall offer improved system efficiency and reduced operation cost.
  6. FIBERGLASS SKID MOUNTED The DI mineral tanks shall be skid mounted on a 4" or 6" channeled fiberglass. The skid shall be cross-braced with 4" or 6" channel fiberglass with coped supports. All interconnecting piping shall be the same material as the valve nest manifold piping, and shall be assembled to the fullest extent possible. The inlet and outlet isolation valve connections, brine and drain headers shall terminate inside the skid internal area. All piping shall be suitably supported and anchored to the skid. All electrical wiring shall be complete between the units, and the hydraulic or pneumatic tubing shall be installed as part of the skid package. The entire skid mounted system shall be leak and electrically tested as a unit by the manufacturer.

FIELD SERVICE, TRAINING, START-UP

Start-up, training and service shall be made available through a net-work of authorized service providers. Authorized service representatives shall have extensive knowledge and 10 years of field experience in the industrial water treatment industry. Technical support and parts shall be available from the manufacturer.

**Specifications Subject to Change without notice.

INSTRUCTIONS

Three (3) complete sets of installation, operation and maintenance manuals shall be provided.

GUARANTEES

Attrition loss of mineral is guaranteed not to exceed 3% per year for a period of three (3) years. All mechanical and electrical equipment is guaranteed for eighteen (18) months from date of shipment or one (1) year from date of service against any defects in workmanship or material. Any part proving defective shall be replaced or repaired within this period at manufacturer’s option. The manufacturer guarantees that under actual operating conditions the mineral shall not be washed out of the system during the service run or backwashing period; and that the turbidity and color of the effluent by reason of passing through the softener system, shall not be greater than the incoming water; and that the underdrain system, gravel and minerals shall not become fouled, either with turbidity or by dirt, rust or scale from the softening system while operating as noted in manufacturer’s instructions.
