ASTM D4692-01(2010) 反渗透和纳米渗透用硫酸盐标定盐分(CaSO4,SrSO4和BaSO4)的计算和修正的标准实施规程

In the design and operation of reverse osmosis and nanofiltration installations, it is important to predict the CaSO4, SrSO4, and BaSO4 scaling properties of the concentrate stream. Because of the increase in total dissolved solids and the increase in concentration of the scaling salts, the scaling properties of the concentrate stream will be quite different from those of the feed solution. This practice permits the calculation of the scaling potential for the concentrate stream from the feed water analyses and the reverse osmosis or nanofiltration operating parameters. Scaling by CaSO4, SrSO4, and BaSO4 will adversely affect the reverse osmosis or nanofiltration performance. This practice gives various procedures for the prevention of scaling.1.1 This practice covers the calculation and adjustment of calcium, strontium, and barium sulfates for the concentrate stream of a reverse osmosis or nanofiltration system. The calculations are used to determine the need for scale control in the operation and design of reverse osmosis and nanofiltration installations. This practice is applicable for all types of reverse osmosis devices (tubular, spiral wound, and hollow fiber) and nanofiltration devices. 1.2 This practice is applicable to both brackish waters and seawaters. 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

ASTM D4516-00(2010) 反渗透性能数据的标准化的标准实施规程

During the operation of an RO system, system conditions such as pressure, temperature, conversion, and feed concentration can vary, causing permeate flow and salt passage to change. To effectively evaluate system performance, it is necessary to compare permeate flow and salt passage data at the same conditions. Since data may not always be obtained at the same conditions, it is necessary to convert the RO data obtained at actual conditions to a set of selected constant conditions, thereby standardizing the data. This practice gives the procedure to standardize RO data. This practice can be used for both spiral wound and hollow fiber systems. This practice can be used for a single element or a multi-element system. However, if the RO system is brine staged, that is, the brine from one group of RO devices is the feed to a second group of RO devices, standardize the permeate flow and salt passage for each stage separately. This practice is applicable for reverse osmosis systems with high rejections and with no significant leaks between the feed-brine and permeate streams.1.1 This practice covers the standardization of permeate flow and salt passage data for reverse osmosis (RO) systems. 1.2 This practice is applicable to waters including brackish waters and seawaters but is not necessarily applicable to waste waters. 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
