14-02: Lessons Learned from a HERO-Based ZLD SystemA critical topic that continues to be discussed at CTI meetings is the need for water conservation across a broad spectrum of industries and municipal applications. More and more, plant personnel are looking at cooling tower blowdown recycle and recovery as a method to conserve water. An emergency technology is water recovery based on the high efficiency reverse osmosis (HERO) technology. This process includes ultrafiltration, softening, and reverse

Today's trends are towards developing larger generating stations at each site

Aside from such possible questions as which of several offerings is more conservatively rated or represents higher quality materials (questions which are outside the scope of this paper) there remains the question of which offering represents the lowest total cost as the buyer seas it

Also discussed are uses and benefits

This program is in progress and additional data will be includes as it is developed

Liquid biocides continue to be a popular choice for control of microorganisms in industrial water systems and numerous treatment options exist in both oxidizing and non-oxidizing biocide categories

A technical review of the fundamentals of high voltage PWT (Physical Water Treatment) systems will be presented

These waters often contain impurities that serve as nutrients for microbiological fouling in cooling systems

The State and Federal regulatory bodies are expected to sanction control stand­ards that will negate the use of chromates and zinc without acceptable disposal methods
