 | A co-generation system of gas and steam turbines continually converts methane gas and heat from sludge combustion to electrical power. | |
 | The Environmental Monitoring Division uses the most technologically advanced equipment and procedures in monitoring the total environmental surrounding Los Angeles' four wastewater treatment plants. |
 | Anaerobic digesters have produced methane gas, a valuable source of energy, by fermenting sludge in an oxygen-free environment since the Hyperion Treatment Plant first began operation in 1950. |
 | Energy-efficient sludge dehydration produces a dry powder used as fuel in thermal processing. The energy recovery system has the capacity to generate 25,000 kilowatts of electrical power. |
 | A special truck loading facility can transfer all dewatered sludge produced into covered trucks if necessary, and has the capacity to hold three days production of sludge. Such storage is often valuable during inclement weather. |
 | A close look at a Gorgonian coral and spider crab is captured by a special camera used in monitoring the number of species on the rocky Santa Monica Bay floor. The health of Santa Monica Bay's marine environment is an ongoing priority of the Hyperion Treatment Plant. |
 | Aeration basins were retrofitted with a more efficient air diffusion system. As a result, secondary treatment facilities process an additional 100 mgd. |
 | The first wastewater treatment process at Hyperion was a simple screening facility that began operation in 1925. |
 | Construction for full secondary treatment was begun in 1991 and completed in 1998 makes the Hyperion Treatment Plant of the next century a world leader in quality wastewater treatment and responsible environmental protection. |
