1.HEDP waxaa loo isticmaalaa sida miisaanka iyo xannibaadda daxalka ee wareegga nidaamka biyaha qabow, beerta saliidda iyo kuleyliyeyaasha cadaadiska hooseeya ee beeraha sida tamarta korontada, warshadaha kiimikada, birta, bacriminta, iwm.
2.In warshadaha tolmo fudud, HEDP waxaa loo isticmaalaa sida saabuunta biraha iyo nonmetal. Warshadaha midabaynta, HEDP waxaa loo isticmaalaa sida stabilizer peroxide iyo wakiilka dheeha-hagaajinta;
3.In electroplating non-cyanide, HEDP waxaa loo isticmaalaa sida wakiilka chelating. Qiyaasta 1-10mg/L ayaa la door bidaa sida xakameeyaha miisaanka, 10-50mg/L sida daxaleeyaha, iyo 1000-2000mg/L sida saabuunta.
4. Badanaa, HEDP waxaa loo isticmaalaa polycarboxylic acid.
