本powerpoint演示文稿介绍了一项关于减少密歇根州荷兰水处理厂（HWTP）污泥产量的研究。 研究发现，选择 在HWTP中添加合适的混凝剂可以显著提高反应速度 工厂的整体工艺性能，包括废水质量， 化学品成本、污泥生产、过滤器操作和 操作控制。在测试的替代品中，alumer最符合 工厂污水处理目标 质量、化学成本、污泥产量和过滤器 活动 进一步的过程性能改进正在进行中 通过优化明矾和 聚合物进料速率独立（而不是使用 预制混合物）。

This powerpoint presentation presents a study on reducing sludge production at the Holland Water Treatment Plant (HWTP), in Holland, Michigan. The research found that selection of a proper coagulant in the HWTP could significantly improve the plant's overall process performance, including effluent quality, chemical cost, sludge production, filter operation, and operational control. Among the alternatives tested, alumer best meets the plant's treatment objectives with respect to effluent quality, chemical cost, sludge production and filter operation. Further process performance improvements are expected to be achieved by optimizing alum and polymer feed rates independently (rather than using a pre-manufactured blend).
