What is SDI?

Activated Carbon
These units remove chlorine, chloramines and dissolved organic contaminants. Each replacement carbon unit contains virgin carbon to assure maximum water quality and service life of the bed.

Cation Resin
Cation resins remove positively charged dissolved ionic contaminants such as calcium, sodium, magnesium, potassium, iron and manganese. The cation resins used are very durable to provide stability against osmotic, thermal and impact shock.

Anion Resin
Anion resins remove negatively charged dissolved ionic contaminants such as carbonate, bicarbonates, sulfates, chlorides, nitrates and silica. The anion resins used offer stability against osmotic, thermal and impact shock. A variety of anion resins are available suitable for any water application.

Mixed Bed Deionizers
For higher quality water with a more neutral pH than separate bed systems, as well as enhanced silica and CO2 removal mixed bed deionizers can be stand alone systems or placed as a polisher after the separate two beds (cation & anion resins). LT Technologies SDI units produce the quality of water required for any application, up to 18.3 megohm resistivity at 25 degrees C. In-line quality monitors immediately alert users when resin tanks need to be changed.

L&T Technologies has full ion exchange resin regeneration capabilities along with quick response time on delivery and troubleshooting. Our regenerated resins are put through testing to ensure that the capacity and purity of the water meets specific requirements for the client’s process. Furthermore innovative measures are taken, that increases the life of the resin and reduces exchange frequency without sacrificing water quality. This in turn reduces costs associated with premature service visits by our service technicians. To reduce suspended matter all organic absorption Medias (carbon) are pre-washed prior to being placed within the treatment process.

L&T Technologies offers a full line of filter and resin canister replacement services that are priced on monthly, quarterly or as required basis. Furthermore full system preventative maintenance programs are available that encompass:

Instrumentation calibration
System operation training and consulting
Filter replacement
SDI (service deionization) exchange
Spare part replacement
Influent and effluent water analyses with engineering feedback

All preventative maintenance and service contracts along with service deionization can be spread out on monthly payment plans. This program is referred to as our “GMP” (Guaranteed Maximum Pricing) pricing plan. After a site visit and incoming water samples are taken and analyzed in our in-house laboratory a proposal is presented that illustrates the water usage and savings with our SDI services. Moreover if required a delineated system and instrumentation service contract is written and included within the “GMP” pricing structure.
