1994年，卡梅尔区污水处理区卵石滩社区服务中心 蒙特利半岛水管理区和卵石滩公司 成立了一家公私合营企业，生产和输送用于灌溉的循环水 前往加利福尼亚州卵石滩的七个高尔夫球场，包括举世闻名的卵石滩 海滩高尔夫球场。通过这次冒险，他们开始了水回收项目， 包括砂滤三级处理，然后进行氯消毒。不多时 新的三级设施开始运营后，卵石滩高尔夫球场开始运营 草坪出现了一些问题，尤其是在果岭上。这是 发现主要是高钠浓度（有时高达 200 mg/L）和高总溶解固体（TDS）浓度（有时高达1000 毫克/升）。为了解决这个问题，该财团与高尔夫球场主管一起， 草坪专家和Carollo工程师开始了盐度管理项目 旨在改善水质，增加再生水的数量 可用于灌溉。 由于早期的讨论，草坪的水质 标准包括最大钠浓度55 mg/L，最大钠浓度 吸附比（SAR）为3.0，最大调整SAR为4.0，电导率 范围为350至450微mhos/cm[相应的TDS范围约为225至 290mg/L]，pH范围为6.3至7.3。微滤（MF），然后是反渗透 （RO）的选择符合该水质标准。MF也将允许治疗 设施继续满足加利福尼亚州第22条关于无限制使用 循环水。几种化学加料系统，如氢氧化钙和石膏， 还包括有助于满足草坪水质标准，并有助于稳定环境 腐蚀性反渗透。包括表格、数字。

In 1994, the Carmel Area Wastewater District, Pebble Beach Community Services District, Monterey Peninsula Water Management District, and Pebble Beach Company formed a public/private joint venture to produce and deliver recycled water for irrigation to seven golf courses in Pebble Beach, California, including world-renowned Pebble Beach Golf Course. Through this venture they began the Water Reclamation Project, including tertiary treatment by sand filtration followed by chlorine disinfection. Shortly after start of operation of the new tertiary facilities, the Pebble Beach golf courses began experiencing some problems with the turf grass, particularly on the greens. This was discovered to primarily be the result of high sodium concentrations (at times as high as 200 mg/L) and high total dissolved solids (TDS) concentrations (at times as high as 1000 mg/L). To remedy the problem, the consortium, along with golf course superintendents, turf grass specialists, and Carollo Engineers, began the Salinity Management Project with the intent of improving the water quality and increasing the quantity of recycled water available for irrigation. As a result of early discussions, the turf grass water quality criteria included a maximum sodium concentration of 55 mg/L, maximum Sodium Adsorption Ratio (SAR) of 3.0, maximum adjusted SAR of 4.0, electro-conductivity range of 350 to 450 micro-mhos/cm [corresponding TDS range of approximately 225 to 290 mg/L], and pH range of 6.3 to 7.3. Microfiltration (MF) followed by reverse osmosis (RO) was selected to meet this water quality criteria. MF will also allow the treatment facilities to continue to meet the California Title 22 requirements for unrestricted use of recycled water. Several chemical feed systems, such as calcium hydroxide and gypsum, are also included to help meet the turf grass water quality criteria and to help stabilize the corrosive RO permeate.
