leg­is­la­tion and en­vi­ron­men­tal de­mands, ac­cu­rate mea­sure­ment and con­trol of waste­water pa­ram­e­ters is es­sen­tial for the treat­ment of ef­flu­ents to re­duce the im­pact of in­dus­try on the en­vi­ron­ment.

The sim­plest and most use­ful of these is pH, the mea­sure­ment of acid­ity and al­ka­lin­ity of the so­lu­tion. pH is one of the most com­mon an­a­lyt­i­cal mea­sure­ments used in process con­trol as many chem­i­cal re­ac­tions rely on the pH of a process be­ing main­tained at the cor­rect value. By us­ing ac­cu­rate pH mea­sure­ment it is pos­si­ble to au­to­mate and im­prove the ef­fi­ciency of a process min­imis­ing waste and re­duc­ing costs.

pH in­stru­men­ta­tion and sen­sors used to mon­i­tor the ef­flu­ent from a fac­tory can iden­tify if the ef­flu­ent re­quires treat­ment be­fore it is dis­charged within the re­quired con­sent lev­els. This min­imises the ef­fects of the waste on the en­vi­ron­ment en­sur­ing op­er­a­tors com­ply with lo­cal leg­is­la­tion and laws.

LTH pro­vide pH equip­ment for use in many in­dus­tries in­clud­ing metal fin­ish­ing, biotech­nol­ogy, mu­nic­i­pal and in­dus­trial waste water.

In­stru­mat­ics’ pH elec­trodes and Re­dox elec­trodes are avail­able in many dif­fer­ent con­fig­u­ra­tions for tank or pipe mount­ing ap­pli­ca­tions. Self-clean­ing and spray wash adapters can be fit­ted to the elec­trodes to re­duce main­te­nance in waste streams that nor­mally coat the elec­trode. The cor­re­spond­ing LTH In­stru­men­ta­tion can be con­fig­ured to con­trol the clean­ing cy­cles and amounts of clean­ing so­lu­tions used.
