HD series SAC softener systems produce zero hardness on produced water with a TDS up to 7000 PPM TDS. This configuration uses a regeneration technique with high concentration salt solution to regenerate the polishing softener counter-currently, possible and then direct the brine to the primary softener at a more efficient concentration in a co-current fashion to obtain the highest capacity. Proven methods and designs allow the lowest hardness leakage.Optional control valves are incorporated to gas scour or surfactant clean the ion exchange resins when they are fouled with oil. The materials of construction are compatible with produced water at temperatures up to 200ºF.
Our WAC softener designs are the best in the industry and capable of producing a low hardness level of 0.2 PPM on produced water with a TDS up to 18,000 PPM. Regeneration using HCl and NaOH is highly efficient with our design utilizing a lower strainer plate and dedicated regeneration distributors. The materials of construction are suitable for high temperature, corrosive operation, and exposure to aggressive regeneration chemicals.
This special design uses select chelating IX resin capable of removing hardness to 10 PPB on concentrated brine to produce a high quality brine that can be used in a membrane cell electrolyzer for the production of chlorine and caustic. The design and materials of construction are critical, especially the choice of elastomers, which need to be resistant to any hardness leaching during operation. Regeneration is performed using HCl and NaOH with a lower strainer plate and dedicated regeneration distributors. This service is very demanding and requires the most efficient design to obtain this quality.
We can provide regeneration stations with our softeners, including: brine makers, HCl and NaOH storage tanks and dosing pumps, and neutralization systems for regeneration waste. We offer monitoring equipment to allow for recycling of waste water to reduce the volume of concentrated waste. These systems can be automated using the PLC controls supplied with the softener trains.
