1. PROCESSING OF WATER AND PROTECTION OF ENVIRONMENT PERTEMUAN 13 Matakuliah: S0372 – Kimia Teknik Sipil Tahun: Ganjil 2007/2008

2. Bina Nusantara ANTECEDENT Problem of amount, quality of, recycle and contamination of water represent very complex problem, so that to chosen from various alternative of is source of optimum processing and water of facet of is expense of, needed by study which circumstantial enough. Decision is usually taken on the basis of consideration of plan its use in product or process of product, etc.

3. Bina Nusantara PROCESSING OF WATER Processing of water (water conditioning) have to be arranged as according to plan usage of that water. Every industry have conditions of processing of its own water for example water for the wash of its textile have to zero, in order not to happened precipitation of calcium soap and magnesium at clothes. Calcium salt, iron and magnesium can cause the happening of precipitation which do not desire at colourant additional admixture in textile industry and paper.

4. Bina Nusantara Method Purification and mellowing of water can be conducted variously, base on plan usage of itself water. Mellowing term (softening) used for process removing or lessening kesadahan of water. Purification namely remove organic materials and mikroorganisme of water. Classification sometime vitally and used at the same time with precipitation in course of mellowing of cool water.

5. Bina Nusantara Water Waste Urban Line of least resistance for the dismissal of that waste is by thinning it; that waste is thrown into body irrigate like lake and river of yg after some times organic waste will fall to pieces by oxygen of yg there are that underwater. But way of this thinning cannot be let again, including at place which that thing admit of to be conducted without endangering. Existing water this time have fallen short again to thin waste of yg its volume have in such a way many, effect of growth of industry and resident.

8. Active Mud represent most effective method to remove suspensions materials and also is dissolve the than waste water. Active mud contain aerobik mikroorganisme able to digest raw waste. Some of active mud which come from former processing included into raw waste, and air blown sufficiently into him and in moderation. Way of dismissal of solid additional chemical result of sweeping of this process depended from local condition. Sometimes that solid additional chemical buried, to be burned, or sold as manure after filtered and dried.
