Water Treatment Evapratin cling is accmplished by the evapratin f a prtin f the water being recirculated.as this water evaprates,the disslved slids riginally present in the water remainin the system.thus,the cncentratin f disslved slids in the circulating water increases rapidly and cntinues as lng as the unit is in peratin. If this buildup is nt cntrled,cncentratins can rapidly reach levels f 750 t 1000 times the cncentratin in the riginal supply water. Additinally,the recirculating water is ften further cntaminated by airbne impurities that may be present in the vicinity f the unit such as chemical fumes in an industrial area r salt near the castline. If the cncentratin f these disslved slids and impurities is nt cntrled,scaleing, sludge, r crrsin can ccur which will reduce the perating efficiency and shrten the life f the equipment. T prevent an excessive buildup f impurities in the circulating water, it is recmmended that a small amunt f water be bled frm the unit at a rate f 0.00 (m /hr) water per 1000 (m /hr) air delivery, is satisfactry fr the usual perating cnditins in mst lcatin. In many lcalities, this cnstant bleed and replacement with fresh water will keep the cncentratin f impurities in the system at an acceptable level. The evapratin rate can be determined by the fllwing: evapratin rate (m /hr) =air delivery (m /hr )w -w (kg / kg )/ air specific vlume (m /kg) ρ ( kg/m ) 1 misture dry air water Example: Given : Air delivery -------------------------------------------------------------------------- 4000 (m /hr) DBin------------------------------------------------------------------------------------ 5 C WBin ----------------------------------------------------------------------------------- 1 C Air velcity --------------------------------------------------------------------------.5 (m/sec) Air Washer--------------------------------------------------------------------------- Class 8 Slutin: With reference t table 5 air washer efficiency=0.84 thus DB ut=.

CHEMICAL TREATMENT If the cnditin f the water is such that cnstant bleed-f f will nt cntrl scale r crrsin,chemical treatment may be necessary.if a water treatment prgram is used it must meet the fllwing requierments: 4
1. The chemical must be cmpatible with galvanized (zinc cated) steel. Water treatment chemicals which are cmpatible with galvanized steel are als satisfactry fr the Zinc Chrmatized Aluminium finish.. The PH f the circulating water must be maintained between 6.5 and 8.5. Chemicals shuld be fed int the recirculated water, but nt int the cld water sump,n a cntinius metered basis t avid lcalized high cncentratins which may cause crrsin.these chemicals are nrmally fed int the pump discharge line. Batch feeding f chemicals des nt affrd adequate cntrl f water quality and is nt recmmended. 4. Acid water treatment is nt recmmended.
