This paper will describe the use of non-chemical technology for the treatment of cooling water from evaporative condensers at a citrus facility. The technology used is Controlled Hydrodynamic Cavitation (CHC). CHC is one of the most innovative technologies employed today and is unlike all other non-chemical technologies currently available that provide scale, corrosion, and microbiological control in addition to water conservation. The objectives of this study conducted in 2003–2004 were to: (a) provide scale, corrosion, and microbiological control to a state-of-the-art facility which cools one of the largest refrigerated enclosures in North America, (b) improve condenser operating efficiency over the existing condenser systems, (c) conserve water by minimizing condenser makeup, (d) produce a reduced quantity of condenser bleed with reduced levels of contaminants, and (e) implement environmental improvements and worker safety wherever possible. Based on the data obtained from the study, all objectives were met, operating expenditures were reduced, and the facility successfully continues to use the CHC technology.

Scale Inhibition

Physical polarization Water Treatment (PPWT) is a new technology that takes advantage of polarization electric field polarizing water molecules to achieve the purpose of scale inhibition and dissolution as well as killing bacteria and algae. The PPWT device made by Shandong Langkun Energy Conservation & Environmental Protection Technology Co., Ltd and running in the biomass power plant of Shandong Kaitai Group Co. achieved the effects of scale inhibition and solution which are even more superior to the traditional method of chemical dosing. It brings annual water conservation of 147600 m3 and economic benefits of hundreds of thousands to millions for forsaking chemical dosing for a 15MW power unit. Therefore, Considerable economic and social benefits and the goals required by the state to the enterprises of energy saving, emission reduction and environmental protection are achieved.

AbstractTo elaborate efficient and economical water supply systems is one of the main objectives in the sanitation companies water system projects. In order to address the challenges faced in reaching this objective, this study aims to identify, first, the relation between the percentage of non-conformed samples in treated water and the inefficiency of the filtering units installed in the water treatment plant, and second, if, by drawing the consumption variation curve it is the most efficient way to predict the storage tanks volume—comparing necessary capacity, determined by the consumption curve, and installed capacity, predict by the outdated Brazilian normative. In order to reach answers for these two questions, this study measured the operating efficiency of the treatment plant as well as have set a quantitative comparison between the two dimensioning criteria for storage tanks volume present in the literature. As a result, the analysis provided the authors to detect a focus of contamination in the single-layered filtering units, limited by the filtering capacity of 2–6 m3/(m2 day), whilst operating at 333.13 m3/(m2 day). As well as to detect by the drawing of the consumption variation curve an oversize of 68% and 60% in the dimensioning of the studied storage tanks. With the results provided by this analysis approach, it was possible to efficiently detect and correct critical impairments in the treatment phase and to conclude that a long-term analysis should be drawn in order to affirm if the consumption variation curve is the best design methodology for the reservoirs.
