Avoid the Springtime Blooms

Even the most well-run wastewater treatment plants may experience effluent quality issues in the spring, when reddish blooms often appear in the final clarifiers and cause higher TSS. These reddish blooms are caused by a proliferation of ceriodaphnia (water fleas). This is the same organism used in the effluent toxicity testing required by discharge permits. […]
